[libcamera-devel] [PATCH] utils: ipu3-capture.sh: Fix the script to work with recent media-ctl versions

[Hans de Goede]

Recent media-ctl versions include the framerate in the fmt property output:

- entity 37: ov5693 4-0036 (1 pad, 1 link)
             type V4L2 subdev subtype Sensor flags 0
             device node name /dev/v4l-subdev6
	pad0: Source
		[fmt:SBGGR10_1X10/2592x1944 at 1/30
		 crop.bounds:(16,6)/2592x1944
		 crop:(16,6)/2592x1944]
		-> "ipu3-csi2 1":0 [ENABLED]

This resulted in $sensor_size getting set to: "2592x1944 at 1 30", which
causes the script to fail.

Fix this by:

1. Replacing the gsub() to remove the '/' between e.g. SBGGR10_1X10
and 2592x1944 with a sub() so that only that first '/' gets replaced
(resulting in a $sensor_size of "2592x1944 at 1/30" instead).

2. Adding a new sub() to remove the @1/30 suffix.
